Marthasville Man Held Without Bond, Accused of Choking Woman After Pool Cue Threat
WARREN COUNTY, Mo. — The woman said she ran when Justin Lambert Karll pointed a pool cue toward her. What happened after he caught up with her is now at the center of a felony domestic assault case.
Karll, of Marthasville, is in custody following the November 9 incident. Judge Jonathan Andrew Yelton issued a warrant the next day ordering him held without bond.
Justin Lambert Karll — Marthasville, Missouri
CHARGES
Second-degree domestic assault — Class D felony
Investigators contacted the woman around 1:45 a.m. November 9. She described an encounter that began with Karll locking her outside the residence.
After she got back inside, she said, he became verbally aggressive. When he pointed a pool cue in her direction, she tried to get away.
She told investigators he caught her and placed her in a headlock.
The woman said Karll took her to the ground, got on top of her and put his hands around her neck, restricting her breathing.
During the assault, she told investigators, he repeatedly said, “I’m done, I’m done.”
She pleaded with him to stop because she could not breathe.
The investigator taking her account reported seeing substantial red markings around her neck and across the top of her chest. Her bottom lip was injured and covered with a dried red substance resembling blood.
Bruising also appeared to be developing beneath her left eye, extending toward the bridge of her nose.
The woman attributed her injuries to the encounter. The probable cause statement describes the pool cue being pointed toward her but does not allege that Karll struck her with it.
The statement places the alleged assault between approximately 1:30 and 1:38 a.m. It lists Karll’s arrest later that day at 1:18 p.m.
The November 10 warrant identified him as already in custody. In ordering no bond, the court found that no combination of monetary or nonmonetary release conditions would secure the safety of the community or another person.
The case is filed in Warren County Circuit Court under 26BB-CR00822. The provided Case.net listing did not show a scheduled hearing.
Karll is presumed innocent unless and until proven guilty in court.
